== Function == | |||
[https://www.uniprot.org/uniprot/ETHE1_ARATH ETHE1_ARATH] Sulfur dioxygenase that plays an essential role in hydrogen sulfide catabolism in the mitochondrial matrix. Hydrogen sulfide (H(2)S) gives rise to cysteine persulfide residues. ETHE1 consumes molecular oxygen to catalyze the oxidation of the persulfide, once it has been transferred to a thiophilic acceptor, such as glutathione (R-SSH). Plays an important role in metabolic homeostasis in mitochondria by metabolizing hydrogen sulfide and preventing the accumulation of supraphysiological H(2)S levels that have toxic effects, due to the inhibition of cytochrome c oxidase. Required for normal endosperm development in seed, and thereby also required for normal embryo development.<ref>PMID:22786886</ref> | |||

== Publication Abstract from PubMed == | |||
The protein product of gene At1g53580 from Arabidopsis thaliana possesses 54% sequence identity to a human enzyme that has been implicated in the rare disorder ethylmalonic encephalopathy. The structure of the At1g53580 protein has been solved to a nominal resolution of 1.48 Angstrom. This structure reveals tertiary structure differences between the ETHE1-like enzyme and glyoxalase II enzymes that are likely to account for differences in reaction chemistry and multimeric state between the two types of enzymes. In addition, the Arabidopsis ETHE1 protein is used as a model to explain the significance of several mutations in the human enzyme that have been observed in patients with ethylmalonic encephalopathy. | The protein product of gene At1g53580 from Arabidopsis thaliana possesses 54% sequence identity to a human enzyme that has been implicated in the rare disorder ethylmalonic encephalopathy.
